WRIST-WATCH. FASTENING.

Patented Oct. 8, 1918.

Application filed November 20, 1917. Serial No. 202,988.

To all whom it may concern:

Be it known that I, VICTOR Simon, a c1 t1- zen of the United States of Amerlca, residing at New York city, borough of Manhattan, county and State of New York, have invented certain new' and useful. Improve.

ments in Wrist-Watch Fastenings, of which the following is a specification.

My invention relates to fastening means for the loops or bands used to secure wrist Watches upon the person of the wearer and presents a simple, readily detachable and adjustable device for holding'the free end of the band which is usually looped around the wearers-wrist, passed through an ear upon the watch case and then doubled back for attachment to an intermediate portion of said band.

A device of this character must be easily and quickly attachable and detachable by the free hand of the wearer, and easily-adjustable to wrists of different sizes. It should also be simple and free from moving parts which would be apt. to break or get out of adjustment under conditions existing on a battle front. My present invention attains these objects and certain, advantages hereinafter to be set out. The best form of apparatus at present known to me embodying my invention is illustrated in the accompanying sheet of drawings in which,

Figure 1 is a perspective view of the in- Vention as appliedto a wrist watch.

Fig. 2 is a longitudinal centralsection on line 2--2 of Fig. 1,'except that parts are shown in the position assumed justprior to disengagement, parts being broken away.

Fig. 3 is a similar view showing the parts in the positions assumed at the moment of disengagement, and

Fig. 4 is a cross section online 4-4 of Figs. 1 and 2.

' Throughout the drawings like reference.

characters indicate like parts: 1, is the watch case having ears 2, and 3, to which the wrist band 4, is attached. One end of the band, as 5, is permanently attached to one watchcase ear 2, and the other free end passes through the other ear 3, and is looped back for a detachable, adjustable connection to an intermediate portion of the band, all as shown in Fig. 1.

The invention comprises the adjustable, easily detachable fastening for the free end of the band, formed of the buckle frame 6, (which can be slid along band 4, for adjustment when the. band is loose but which grips 1t frictionally when the band is under tension), and means by which the free end. of the band may engage the buckle frame.

The buckle frame 6, has a plurality of parallel bars, (preferably three in number), all arranged in substantially the same plane and separated by narrow slots through which the band 4, passes under the inner bar 7, and over the outer bars 8, 8. On the upper side of bar 7, is mounted the hook 9, substantially midway between the upturned sides 10, 10, of the buckle frame. These upturned sides which form side guides for the engaging band end are preferably roughened on their exterior surfaces as shown at 11, 11, in Fig. 1. V

The free end. ofband 4, has a hole 12, preferably reinforced by an eyelet 14. The tip of the band projects some distance beyond the holev 12, and is stiffened around and beyond the hole by a tip 13, of metal or otherstifi' material.

The parts are so proportioned, preferably, that the band and tip '13, fit snugly in between side guides 10, 10, and the hook 9, is low enough in relation to the upper surface of band 4, to cause the free end and tip of the band to slightly compress the adjacent cam-like portions of said band which are overlying outer buckle bars 8, 8, when the band end is engaging the hook, as shown in Fig. 2. Accordingly, when the end of band 4, is forced away from 9, in the act of disengaging, as shown in Fig. 3, the cam-like portion 15 of the band reacts, both on account of its resiliency and its cam-like surface and tends to lift the tip 13, and free hole 12, from engagement with hook 9. If, as is usual, the operator also raises the band 4, at the point where he seizes it, the stiffened tip 13, further acts to insure a ready disengagement from the hook as illustrated in Fig. 3.

To adjust the loops to the wrist of the wearer, the buckle frame 6, is grasped by the roughened side portions 11, 11, and slidas from being stretched around the wearers wrist, friction will hold the buckle frame in its adjusted position.

The advantages of my invention comprise its simplicity, and freedom from moving parts. There are no pivots, or teeth, or hinges, or similar parts to get out of order or rust into uselessness. The fastening is secure when in operative position and yet can be readily disengaged with the use of the thumb and forefinger of the wearers free hand. There are no sharp projections to catch in the clothing or scratch the skin of the wearer.

Various changes could be made in the details of construction here shown and described without departing from the underlying principle of my invention so long as the general arrangement of parts and principles of operation above set forth are preserved.

Other detachable fastening means might be substituted for the specific form shown in the drawings, 2'. c. the hook and engaging eyelet, and other forms of buckle frame might be employed, without depriving the construction of the advantages resulting from the use of the stiffened tip for the free.

end of the band associated with the fastening member on said free end. This tip 13, performs a number of most important functions. Incidentally it prevents the raveling of the free end of the band without adding appreciably to the thickness thereof, but itsmain advantages reside in the fact that the stifi'ening of the end of the band around and beyond the fastening means prevents said end from curling up to catch in the wearers clothing or other object and producing an.

undesired disengagement, while it facilitates any desired disengagement when properly manipulated, as illustrated in Figs. 2 and 3. Any such tendency of the tip 13, to cant or curl up is further prevented, when the parts are in engagement as shown in Fig. 1, by the other cam-like portion 16, of the band 4, upon which the rear or inner end of tip 13, rides, and which tends to force said rear end upward. This makes the tip 13, in effect a lever with its fulcrum at the point of engagement with hook 9, and positively forces the outer end of the tip: down into close contact with band 4. Preferably the eyelet 14, or other fastening means carried by the free end of the band passes through, and is positively clamped to, the stiffening tip 13, as shown in Fig. 4. The tip stiffener ment to wrist watches and the like the combination with a buckle frame having a plurality of parallel bars in substantially the same plane and close together and an upwardly projecting hook on an inner bar, of a band of compressible material passing through the slots between the bars and under the bar carrying the hook, said band having a hole near its end for engaging said hook and a stiffening tip portion extending around and beyond said hole.

2. A structuresuch as set forth in claim 1, in which the hook is shaped to cause a slight compression of the portion of the band engagingv it against the supporting portions of the band which lie over the ad jacent parallel bars of the buckle frame.

3. In a loop fastening device for attachment to wrist watches and the like the combination with a buckle frame having a plurality of parallel bars in substantially the same plane andclose together and an upwardly projecting hook on one of said bars,

ing the hook, and having a hole near its free endfor engaging the hook, said buckle frame having upwardly turned side pieces shaped to serve as guides for the portions of the band lying between them, which side pieces are roughened on their outer surfaces to afford the operator a firmer grip when adjusting the position of the buckle frame on the band. V

4. In a looped fastening device for use with wrist watches and the like the combination, with a fiexiblevband adapted to be detachably fastened in a loop form and which has a stiffened portion at andnear its free end, of a fastening member rigidly mounted in said stiffened portion a short distance from the end thereof, and a second cooperating fastening member mounted on an intermediate portion of the band and adapted to detachably engage the first mentioned fastening member, whereby, upon a partial disengagement of the intermeshing portions of the fastening members, the said stiffened portion of the band tip is adapted to serve as a lever for completing the disengagement of said members. 7

5. A structure such as set forth in claim 4, in which .the stiffening agency for the band end comprises an inclosing tip piece of stifi material, and in which the fastening member mounted on the intermediate portion of the band has upwardly projecting side pieces between which the stiff tip mem ber fits snugly when the fastening members are in engagement.

6. In a looped fastening device for use with wrist watches and the like. the combination, with a flexible band to be detachend, of a fastening member mounted in said the band to the rear of the point of engagestiffened portion, a second, cooperating, ment of the fastening members, whereby the fastening member mounted on an intermefront or outer end of said stiffened band por- 10 diate portion of the band, and means exerttion is, during engagement of the fastening 5 ing, When the parts are in engagement, an members, normally held in close contact with outward pressure from the second fastenthe underlying portion of the band. ing member against the stifi'ened portion of VICTOR SENCE.
